public abstract class CameraBridgeViewBase
This is a basic class, implementing the interaction with Camera and OpenCV library. The main responsibility of it - is to control when camera can be enabled, process the frame, call external listener to make any adjustments to the frame and then draw the resulting frame to the screen. The clients shall implement CvCameraViewListener.
